Abstract:
The present study investigated some residues of organochlorine pesticides in the highly consumed types of fish in Egypt, tilapia. 75 Nile tilapia (Oreochromis niloticus) were collected from fishing sites in three areas, Caesarea, Qualidia, and El wasta in Assiut city to detect the extent of the pollution in the city. The residues were analyzed by Gas chromatography–mass spectrometry. Average concentrations of pesticide residues in the muscle of tilapia were estimated. The results showed the presence of different types of organochlorine pesticides in Caesarea, Qualidia, and El-wasta areas in varying degrees. Organochlorine pesticide residue levels have not exceeded the maximum residual limit. Overall, the highest levels of pesticide residues were found in Caesarea and El wasta than Qualidia area.
